Initial analysis

The property at 3561-3565 20th Street is a two-story multi-family residential building with ground floor retail space, constructed in 1880 in San Francisco's Inner Mission neighborhood. The building underwent significant safety improvements in 2019-2020, including the installation of a comprehensive fire sprinkler system (upgraded to NFPA 13 calculations), new underground systems, and related electrical work, with the most recent sprinkler modification occurring in June 2020. A major structural improvement was completed in 2019 with the replacement of the foundation, and the building's electrical system received substantial upgrades, including a 200-amp service upgrade in 2003 and new wiring for a previously unauthorized ADU (Accessory Dwelling Unit) in 2020.

The property has undergone several notable renovations, including a 2012 ground floor retail space remodel to accommodate a cafe with ADA compliance features. Multiple window and door replacements, along with skylight additions, were performed in 2019. Regular maintenance and cleaning have been documented through 311 calls, with the most recent incidents primarily involving sidewalk cleaning and graffiti removal between March and October 2024. While these exterior maintenance issues were promptly resolved, the building's recent history shows consistent attention to fire safety improvements and structural maintenance. The property records indicate proper legalization of previously unauthorized units and framing of improvements, with all major permit work now considered complete.

Risk rating

How 3561-3565 20Th St's risk score is calculated

We trained a model on 7 years of SF DBI inspection data — notice of violation filings, complaint history, and owner track records. It estimates the probability that DBI inspectors will issue a Notice of Violation at this address in the next 12 months. Lower % = safer.

What the score means for you

Grade A–B — Low risk

DBI rarely finds violations here. Strong maintenance history and a clean complaint record.

Grade C — Moderate risk

Some past violations or complaints on record. Worth asking the landlord about any open issues before signing.

Grade D–F — High risk

Elevated violation and complaint history. DBI has found issues here before and is statistically likely to again.

Neighborhood percentile
